Question

Write a problem to simulate the operation of a sequential taillight system. The light system consists of 3 separate lights on each side of the car. East set of lights will be activated separately, by either the left or right turn signal switch. There is to be a 1 second delay between the activation of each light, and a 1 second period when all the lights are off. Ensure that when both switches are on, the system will not operation. Use at least number timers possible. The sequence of the operation should be as follows: the switch is operated Light 1 is on Light 2 is on 1 second later Light 3 is on 1 second later Light 3 is on for 1 second all light are off for 1 second the system repeats while the switch is on. Thank you very much if you can help me with this?
